Brief Summary

The goal of this clinical trial is to investigate the efficacy, safety and tolerability of LM-108 antibody in combination with sintilimab for patients with locally advanced or metastatic Non-Small Cell Lung Cancer patients.

Detailed Description

This study is an open-label, multi-cohort, multi-center clinical trial evaluating the efficacy, safety, and tolerability of LM-108 monoclonal antibody combined with sintilimab in treatment-naïve or previously treated subjects with locally advanced or metastatic non-small cell lung cancer (NSCLC). There are two cohorts in the study:(1)Cohort 1: NSCLC patients who developed secondary resistance after being sensitive to prior treatment with PD-1 inhibitors (monotherapy or in combination with another systemic therapy) for 6 months or more are eligible for this study.(2)Cohort 2: Patients with locally advanced or metastatic NSCLC who have not received prior systemic treatment are eligible for this study.

Subjects in Cohort 1 will receive LM-108 monoclonal antibody combined with sintilimab. Subjects in Cohort 2 will receive LM-108 monoclonal antibody combined with sintilimab and chemotherapy for 4-6 cycles. LM-108 monoclonal antibody combined with sintilimab will be maintained, and the choice of chemotherapy regimen and the duration of use will be determined by the investigator. Treatment will continue until disease progression, unacceptable toxicity, initiation of a new anti-tumor therapy, withdrawal of informed consent, loss to follow-up, death, or other investigator-determined reasons for discontinuation, whichever occurs first, with a maximum treatment duration of 24 months. The primary study endpoint is the objective response rate (ORR) assessed by the investigator based on the Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.

Eligibility Criteria

Inclusion Criteria

• Obtain written informed consent before implementing any trial-related procedures;
• Aged >= 18 years old;
• Patients with locally advanced (stage IIIB/IIIC), metastatic, or recurrent (stage IV) NSCLC confirmed by histology or cytology, who are not candidates for surgical treatment and cannot undergo curative radiotherapy or chemotherapy according to the 8th edition of the TNM staging classification by the International Association for the Study of Lung Cancer and the American Joint Committee on Cancer;
• Absence of the following gene mutations: EGFR gene, ALK fusion oncogene, ROS1, etc. For other types of gene mutations, patients without approved targeted therapies are allowed to be included;
• Cohort 1: Patients with non-small cell lung cancer who have developed acquired resistance to PD-1 inhibitors (alone or in combination with another systemic therapy) after being responsive to treatment (for 6 months or more) can participate in this study. Cohort 2: Patients who have not received any systemic anti-tumor treatment for advanced/metastatic disease before; for patients who have previously received platinum-based adjuvant chemo/radiotherapy, neoadjuvant chemo/radiotherapy, or curative radiotherapy for advanced disease, disease progression occurred more than 6 months after the last treatment, they can participate in this study;
• The investigator confirms at least one measurable lesion according to RECIST 1.1 criteria;
• Estimated life expectancy >= 3 months;
• ECOG PS: 0-1 score;
• Provide archived tumor tissue (including formalin-fixed paraffin-embedded tissue blocks containing tumor [preferred] or approximately 15 freshly cut unstained tissue sections) for confirmation of immunohistochemistry for PD-L1, CCR8, CCL1, FOXP3, etc. If archived tissue cannot be obtained, subjects must agree to undergo a tumor biopsy during the screening period;
• Hematological function is sufficient, defined as absolute neutrophil count >= 1.5×10^9 /L, platelet count >= 100×10^9 /L, hemoglobin >= 90g/L (no history of transfusion within 7 days);
• Liver function is sufficient, defined as total bilirubin level <= 1.5 times the upper limit of normal (ULN) and aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels <= 2.5 times ULN for all patients, or for patients with liver metastases, AST and ALT levels <= 5 times ULN;
• Renal function is sufficient, defined as serum creatinine <= 1.5 times ULN;
• Coagulation function is sufficient, defined as international normalized ratio (INR) or prothrombin time (PT) <= 1.5 times ULN; if the subject is receiving anticoagulant therapy, INR/PT within the range specified by the anticoagulant drug is acceptable;
• Childbearing-age women must have a negative pregnancy test within 7 days before starting treatment; and reliable contraception measures (such as intrauterine devices, contraceptive pills, and condoms) should be used within 30 days of the start and end of the trial. Childbearing-age male subjects should use condoms for contraception during the trial and for 30 days after the end of the trial;
• Cooperate with regular follow-up visits and comply with the requirements of the trial.
